SMTP problem

Hm, well...

we don't know what was running on the server before you installed ispcp. On a fresh installation there are no problems (at least not theese).

a dpkg -l | grep sasl brings this on my server:
libsasl2
libsasl2-2
libsasl2-modules
sasl2-bin

so, could you remove the unneeded packages. Restart postfix and give us feedback.
If it's still not working - you'd better give us the output of "postconf -n" and maybe the master.cf.

Also have a look in the other threads - there are similar thing (most of them did not follow the official install way - or they don't run debian etch...)
